“By repeating the theory of laboratory leaks, the United States will not succeed in discrediting China, but will only damage its own credibility,” Ms. Mao said.

“We urge the United States to respect science and facts … to stop turning origin tracing into politics and intelligence, and to stop undermining social unity and origin cooperation,” she added.
